IMPROVEMENT IN LETTER AND PllC TURE BLOCKS.

. Specification forming part of Letters Patent No. 163,9 l 2, dated J une 1, 1875 application filed May 1, 1875.

' ing the letters for naming the picture and identifying them therewith.

Figures 1, 3, 4, and 5 are plan views of three picture-blocks, with the letters of which their names are composed,connected by notches and projections peculiar to each letter in form and Fig. 2 is a section through Fig. 3 on line w 00.

Similar letters of reference indicate corresponding parts.

A represents the picture-blocks, and B the letterblocks. The picture-blocks are contrived with notches G in the lower edge, and

the letter-blocks have points or projections D, to fit in the notches for arranging the letters to name the pictures; but, unlike other picture and letter blocks for object-teaching, the form of these notches and projections vary with each letter, so that only the right letter will fit the block in the right place, thus distinguishing the letter wanted from all the others, and so serving to instruct the child by this fact, as well as by the letter itself.

Having thus described my invention, 2 claim as new and desire to secure by Letters Patent- 'lhe picture-blocks A, in combination with the letter-blocks B, each of the latter having one of the letters forming the name of the pictured object, and fitting to the block A by means of grooves and projections, which vary in form for the different letters, substantially as and for the purpose set forth.
